I have a long time problem with the latest installs, that my two tv-cards are not producing sound in mythTV.I used a liveCD of MythBuntu, and they worked like a charm.In dmesg, both cards seem to have trouble to get them registered with alsa.The dmesg is filled with errors eg:

The version mismatch has probably something to do with a wrong compiled alsa. Mismatch with kernel version. At least that is what I suspect.Because nobody else has this problem I am going to make changes in hardware, see if that brings me more luckThanks for your help Possy.

Yes ok.Possy did a build with the flags I provided, but it gave more problems and no solutions.So what is the approach?Trying to solve it? revert back to older alsa, or wait till we use newer kernel?

Also after reverting to older alsa, everything is registered nicely, but no sound in MythTVTV works through mplayer -> video0 alsa=hw1,0 etc etc.If I use ALSA:default or the ALSA:hw1,0 in myth-setup, no sound.

I am troubleshooting myself using mythbuntu 0810 and 1004 to see which settings should work.I keep you posted on it

Did a new install. This time a netinstall.Reverted to older version of ALSADid not auto add the card, so I cannot view it in webadmin.Manually added the card in MythTV and used the following for sound ALSA:hw:1,0To be on the safe side I rebooted and voila, sound with TV.

I'm not sure where to put this, but I was having this same problem for a long time with the additional headache that when I downgraded alsa to 1.0.17 I lost my optical out on my realtek ALC888 sound card built into the motherboard. So it was either have the solo microphone and usb soundcards that could be used as squeezeslaves or have optical out. Looking at some posts that focused on this sound card it seemed that the problem might be alsa 1.0.23. So I downloaded and compiled alsa 1.0.24 on my lmce 8.10 setup and then rebooted. Curiously, even though cat /proc/asound/version still showed 1.0.23, something was fixed: I had optical out sound and I could see my usb sound card through squeezeslave -L. I'll keep testing to see if this broke something else but for now I am a happy camper. Just thought this might help someone in the same boat.
